Quality control is nonexistent; would never buy these again
These batteries were physically much thinner than a standard OEM battery, either by design or by manufacturer defect (I don't know which), and it made the batteries nearly useless.
This resulted in the battery having serious fitting issues inside the SX530 HS camera's battery compartment -- pushing the battery into place would only result in the battery popping right back out because it was so thin, the battery retention lever couldn't hold it in place.
I spent about 5 minutes playing "pop goes the weasel" trying to push the battery into place, and close the door before it popped out by itself. I only really succeeded once, when I managed to get the battery retention lever to hold it just long enough for me to shut and lock the battery compartment door.
The batteries themselves seemed to hold a decent charge, but I never bothered to test any of them as all four had the same issues with fitment, and the camera/all batteries have already been resold.
Overall, I would say to avoid this brand by any means necessary -- the SX530 HS is designed to have superzoom for catching wildlife, air shows, events, etc. and with this issue of trying to get the batteries to stay put, you'll probably spend so much time fussing with reloading a new battery that you'll miss your shot.
